SwitchBlox is a small ethernet switch with five 10/100MB ports, specifically designed for space-constrained and noisy environments.
With an overall size of 44.5mm (1.75 inches) by 44.5mm (1.75 inches), SwitchBlox is the smallest network switch in the world, making it perfect for robots, drones, or any space-limited networking application.
Plug and play network switch
As an unmanaged network switch, it works straight out the box, all you need to do is...
- Apply a 5 to 60V DC supply.
- Connect your devices using the included cable set.
- It will automatically begin forwarding packets, no coding or setup needed.
Dimensions
We've squeezed all necessary Ethernet circuitry into SwitchBlox without making performance compromises. We use magnetics for improved signal integrity and electrical isolation between each ethernet bus.
Cabling
We use Molex Picoblade connectors on all our boards to keep them tiny. All boards ship with a cable set included, which consists of...
5 x PicoBlade to RJ-45 300mm (SKU: BB-PBRJ1-4-0.3)
1 x PicoBlade to bare wires 300mm (SKU: BB-PBTL1-4-0.3)
Ethernet Pinout
Below is a handy graphic that shows how we transition from a Molex Picoblade pinout to the standard RJ-45 ethernet cables. For 10/100 Mbps ethernet we use two differential channels, transmit and receive, for a total of four conductors.
Covered under the BotBlox Supply Guarantee Program
This board is covered by our supply guarantee, which guarantees availability and low lead times until at least 2028. Read more about the BotBlox Supply Guarantee Program.
Custom Cables
All our boards are shipped with the required 0.3 meter power and data cables included, so you do not need to purchase extra cables. However if you need custom cable lengths for your application, you can order those here.
